As per this idle thought:
I'd love to be able to purchase past years' DevCon materials, even if they went on sale 6 months to a year after the convention itself. This year will be my first DevCon, so I can't say whether that would negatively impact attendance; I imagine that the in-person experience (and perqs like software, etc.) adds enough value that it makes the trip worthwhile. In fact, the quality of the few videos posted helped convince me to splurge on this year's convention.
Is it or will it become possible to buy session materials from previous DevCons in part or in whole?
